I've never really experienced pad knock-back till last weekend at VIR. Obviously, I know what I need to do to reset them and will now incorporate that as part of my driving routine. But a couple of questions more on the maintenance side -
1) Is this typically an issue with the front or rear pads or both?
2) at what pad depth do you simply get rid of the pads to avoid this problem (as compared to leaving them on to get maximum usage)?
Before last weekend, I put on fresh fronts but rears were three weekends old. But as the weekend wore on, I felt that I was losing braking confidence. We bled brakes just to be sure and that helped minimally.
